Particularly , overexpression of hag 1 in arabidopsis created flower phenotypes resembling that of the apetala2 mutant and ag transgenic arabidopsis plants . this further confirms that hag1 is the ortholog of floral identity gene ag 特别是angi过量表达的转基因植株产生类似qpz突变体的花，并与ag过量表达的转基因植株的表型相似，进一步证实ogi为ag的同源基因。
